| Abstract: | There are some problems in current power grid fault diagnosis system based on expert system such as time-consuming diagnosing and difficulty in on-line expert knowledge maintenance especially in high level dispatching centre. A novel fault diagnosis approach of smart trans- mission grid based on knowledge grid technology was presented for solving problems mentioned above. Firstly, the knowledge grid technology was introduced to smart transmission grid fault diagnosis field. Then the knowledge map of fault d... |
